Show HN: Every mountain, building and tree shadow mapped for any date and time https://ift.tt/HwIPFAu

Show HN: Every mountain, building and tree shadow mapped for any date and time I've been working on this project for about 4 years. It began as terrain only because world wide elevation data was publicly available. I then added buildings from OpenStreetMap (crowd sourced) and more recently from Overture Maps data. Some computer vision/machine learning advancements [1] in the past few years have made it possible to estimate tree canopy heights using satellite imagery alone making it possible to finally add trees to the map. The data isn't perfect, but it's within +/- 3 meters of so. Good enough to give a general idea for any location on Earth. Happy to answer any questions.

Show HN: Brisk a complete CI system is now Open Source https://ift.tt/gM8Oxo0

Show HN: Brisk a complete CI system is now Open Source Brisk is a complete CI system that runs your test suite in seconds. The main speedup over standard CI systems (think CircleCI or Github Actions) is that we maintain your test environments and don't rebuild them on each test run. This allows you to scale up your workers without just scaling up the build time on each test run. Brisk can be run from your local dev environment (the command line or VS Code) allowing your to access the speed of many servers from your local machine or it can be run as part of a traditional CI/CD pipeline (in Github actions etc). I've been working on Brisk for the last few years and I've decided to open source the project. You can now run your own super fast CI service on your own hardware or in your own cloud. https://ift.tt/NdWCwBi https://ift.tt/GvVry5M May 30, 2024 at 04:46AM

Show HN: A New Kind of Chat Room https://ift.tt/RFan8Wt

Show HN: A New Kind of Chat Room I’ve developed an application that reimagines chat rooms by integrating them with a world map. Each user can claim a rectangular piece of land on the map, referred to as a "banner." Users within close proximity are grouped into a chat room by the app. The banner’s size can expand or shrink based on the density of users in the area and the number of coins in the user’s account. Key Features: Real-World Interaction Model: Users are pseudo-anonymous, akin to real-world interactions. Coin balance determines user size and visibility ("stature"), while endorsements and other activities form a unique endorsement chart, serving as a digital representation. This allows for interaction without revealing one’s entire social or professional network. Community Clusters: Users can form open communities based on real-world locations. New users can discover and join these clusters via heatmaps, without needing specific URLs or hashtags. Initial Coins: New users start with 1000 coins. These coins can be used to endorse other users' content, earning stakes in the endorsed banner. When others endorse that banner, the original endorser gains more coins. This endorsement economy is experimental, and could eventually involve crypto tokens. Useful Points: Banner Interactions: Clicking on a banner opens it fully. A button with a chart icon on the top right flips the banner to display the activity chart. Compatibility: The application currently works best on Google Chrome. Heatmap View: Zooming out on the map reveals a heatmap of banners. Side Panel Tabs: First Tab: Displays a feed of content from the visible map area. Second Tab: Contains the cluster chat. Current User Base: At the moment, only my friends and family are using the application, so banners are predominantly found in the Chicago area. For more details, refer to the white paper provided. I’m excited to share this application and look forward to your feedback! https://beescribe.com/ May 28, 2024 at 09:37AM

Show HN: Get paid to do your own ML research https://ift.tt/3TvoARk

Show HN: Get paid to do your own ML research I'm launching an experimental research grant that I call Cat's grant (I'll find a better name later). tldr: - you get paid to do your own research and report to me - you keep IP/ownership rights - 10 months duration - choose a grant size of $10k, $50k or $100k total (paid in monthly chunks) - Apply by sending an email to not_a_cat@fastmail.com How it works: You specify the grant size when applying: 10k, 50k and 100k. This total amount will be distributed over a period of 10 months. I will review each application within 1 week. The deadline to apply is June 9. The start date is flexible and can be the start of June, July, August or September. The total budget I will allocate to this is around 100-200k I haven't yet made a proper contract reviewed by lawyers. If interest is strong enough, I will do it and try hard to keep the spirit of what is said here. The contract will be under Swiss law. Rationale: I get to meet cool people, promote and follow cool research. You get to do the research you want with little red tape (I'll be the sole decision maker for applications. Paperwork will be done with the help of other people). Application process: You choose the grant size you apply for. You can apply to multiple ones at the same time. Then, you may be accepted for one grant option or rejected for all. The process has 3 stages: - Email application - First screening call - Second call with more in-depth questions If you complete the 3 steps, you are accepted in the grant program. Reporting requirements: You are expected to produce the following: - A weekly email report that can be as short as a single sentence (meant as a pulse that you are still here) - A monthly research update that has to be public, in the format you want (github file, blog post…) - Do a monthly call with me, discussing the monthly research update Payment schedule: One payment of 10% of the total amount will be made at the end of each month while the grant is active. The grant may be canceled if the reporting and effort is insufficient. The bar for this will be reasonably low. Effort and time spent will be considered good enough for keeping the Grant active. Research directions: You are free to decide what topic to research. Reading and studying during the research is considered normal. I will try to be helpful and suggest research directions and ideas. I will only consider applications in the domains of Machine Learning, Deep Learning and AI broadly speaking. With a preference for topics related to the following: - LLMs and Transformer architectures - Mechanistic interpretability - World models - Self play / synthetic data - Probabilistic programming Copyright and IP rights: The research remains your intellectual property. You can use it and commercialise it as if you produced it independently of the grant. Time commitment: You are expected to spend at least 50% of your working time on research related to the grant. You may have other commitments at the same time, as long as you can free up enough time. Selection criteria: - How excited I am about the research you want to do - Whether I believe you can make good progress on it - Intrinsic motivation and strong determination How to apply: Send an email to not_a_cat at fastmail com with the following: - Subject: "Application for Cat's Grant [10k, 50k, 100k]". Only keep the grant size(s) that you actually apply for, eg [50k] or [10k, 50k]. - Info about yourself, please include links to github/linkedin and/or resume - Recent projects/research you've done if any - Outline of the research you want to do as part of the grant. It's ok if you only have a vague idea, but better if you have something specific. It can be new or existing research. - Anything else you think is relevant. Evidence of strong capability is a plus, even if unrelated to ML research. Happy to answer questions or comments. May 27, 2024 at 08:24PM

Show HN: Blue Noise – Interactive Explanation of Void and Cluster Algorithm https://ift.tt/1m95QBD

Show HN: Blue Noise – Interactive Explanation of Void and Cluster Algorithm After reading about the generation of blue noise here on HN a few times my goal was to implement my own variant of the the Cluster and Void algorithm in the most straight-foward way possible, while also visualizing each step. (JavaScript is required in order to step through the algorithm) Most other Blue Noise generator implementations are optimized for speed. Many explanations of the Cluster and Void algorithm I found online were overly complicated or focusing on details that do no help the initial understanding. My implementation is optimized for readability and understanding. I find it very inspiring see an algorithm broken down to its most essential steps. For one in order to better understand the algorithm itself but also for transfering its key concepts to other tasks, for example when designing my own algorithms. Eg in my rather high level python/numpy implementation one can easily understand that the two phases of the algorithm (phase 2 and phase 3) have no data dependency between each other and can therefor be parallelized. Additionally the numpy implementation demonstrates how the application of high level concepts like rank-polymorphism and convolution allow to express a sophisticated algorithm in only a few lines of code. Hope you like it. https://ift.tt/FvHhZaj May 28, 2024 at 03:37AM

Show HN: Meal planning – without the mental load https://ift.tt/uecFxPC

Show HN: Meal planning – without the mental load TLDR; I applied the concept of "don't make me think" to the task of selecting meals, and assembling the shopping list for your grocery run. The basic idea for what I wanted is very simple: Rather than making a shopping list, I wanted to create a re-usable 'meal', with a list of ingredients I'd need to add to my shopping list to make that meal. Then, after selecting meals for the week I'd have a quick 'check' step, where I'm prompted to check the cupboard for each ingredient, before it's added to the shopping list (ie: I'll need ground beef to make tacos, but I already HAVE ground beef in the freezer). I originally built this out just for myself, but the result has been such a helpful and stress-free experience that I thought others might appreciate it as well. I think this tool could be well-suited for younger folks that are new to the labour of meal-planning. College students, newlyweds, and families with young children. You can try it out without needing to register or provide any personal information, and I'd love your feedback! https://supperstock.ca/ May 28, 2024 at 12:34AM

Show HN: I generated API documentation for all Java packages https://ift.tt/ON43zB5

Show HN: I generated API documentation for all Java packages Hi HN! I'm excited to share a project I've been working on for the past year: Docland. It is an API documentation browser that generates documentation on demand (through compilation, not LLMs) for Java packages. Instead of relying on Javadoc, the built-in doc generator, I created the engine from scratch to give the documentations a modern look, build fast search indexes, and enable link resolution to other packages. I built Docland because I constantly found it frustrating to locate and view API definitions when programming. You'd have to Google the function/class name, skip all the SEO articles, find the page you want, yet the documentation might be poorly formatted or does not support searching. So I thought it would be really cool to create a documentation site dedicated for programming languages and libraries, so that you can find the docs all in one place with a uniform look. Docland currently only supports Java, but more programming languages can be supported thanks to its modular architecture. Please try it out and let me know what you think! Also, the process of building Docland was extremely fun and challenging. I'm happy to share about that too. Thank you! Martin https://docland.io May 26, 2024 at 06:05PM

Show HN: Spot – Simple, cross-platform, reactive desktop GUI toolkit for Go https://ift.tt/wNMSdJe

Show HN: Spot – Simple, cross-platform, reactive desktop GUI toolkit for Go Hi HN, I’m excited to share Spot, a simple, cross-platform, React-like GUI library for Go. It is just a few days old and has lots of missing features but I'm happy with the results so far, and looking for some design feedback. Spot is designed to be easy to use and provide a consistent API across different platforms (mainly Mac & Linux). It’s inspired by React, but written in Go, aiming to combine the best of both worlds: the easy tooling & performance of Go with a modern, reactive approach to UI development. Key features: - Cross-platform: Leveraging FLTK[1] & Cocoa[2], Spot works on Mac, Linux, and the BSDs with plans for native Windows support in the future. - Reactive UI: Adopts a React-like model for building UIs, making it intuitive for those familiar with reactive frameworks. - Traditional, native widget set: Utilizes native widgets where available to provide a more traditional look and feel. Why I built it: I was searching for a cross-platform GUI toolkit for Go that had a more traditional appearance, and none of the existing options quite met my needs. I then started playing with Gocoa and go-fltk and suddenly I worked on an experiment to see how challenging it would be to build something like React in Go, and it kinda evolved into Spot. ¯\_(ツ)_/¯ In 2024, is there a still place for classic desktop GUIs—even with a modern spin? I’d love to hear your thoughts, feedback, and any suggestions for improvement. Also, contributions are very welcome. Thank you for checking it out!

Show HN: We open sourced our entire text-to-SQL product https://ift.tt/Wp7THAF

Show HN: We open sourced our entire text-to-SQL product Long story short: We (Dataherald) just open-sourced our entire codebase, including the core engine, the clients that interact with it and the backend application layer for authentication and RBAC. You can now use the full solution to build text-to-SQL into your product. The Problem: modern LLMs write syntactically correct SQL, but they struggle with real-world relational data. This is because real world data and schema is messy, natural language can often be ambiguous and LLMs are not trained on your specific dataset. Solution: The core NL-to-SQL engine in Dataherald is an LLM based agent which uses Chain of Thought (CoT) reasoning and a number of different tools to generate high accuracy SQL from a given user prompt. The engine achieves this by: - Collecting context at configuration from the database and sources such as data dictionaries and unstructured documents which are stored in a data store or a vector DB and injected if relevant - Allowing users to upload sample NL <> SQL pairs (golden SQL) which can be used in few shot prompting or to fine-tune an NL-to-SQL LLM for that specific dataset - Executing the SQL against the DB to get a few sample rows and recover from errors - Using an evaluator to assign a confidence score to the generated SQL The repo includes four services https://ift.tt/kj50LoQ : 1- Engine: The core service which includes the LLM agent, vector stores and DB connectors. 2- Admin Console: a NextJS front-end for configuring the engine and observability. 3- Enterprise Backend: Wraps the core engine, adding authentication, caching, and APIs for the frontend. 4- Slackbot: Integrate Dataherald directly into your Slack workflow for on-the-fly data exploration. Would love to hear from the community on building natural language interfaces to relational data. Anyone live in production without a human in the loop? Thoughts on how to improve performance without spending weeks on model training? https://ift.tt/JhsHRld May 23, 2024 at 09:20PM

Show HN: Excel to Python Compiler https://ift.tt/zZJ0qsr

Show HN: Excel to Python Compiler We (me and @aarondia) built a tool to help you turn psuedo-software Excel files into real-software Python. Ideally, Pyoneer helps you automate your manual Excel processes. You can try it today here: https://pyoneer.ai . How it works: 1. You upload an Excel file 2. We statically parse the Excel file and build a dependency graph of all the cells, tables, formulas, and pivots. 3. We do a graph traversal, and translate nodes as we hit them. We use OpenAI APIs to translate formulas. There’s a bunch of extra work here — because even with the best prompt engineering a fella like me can do, OpenAI sucks at translating formulas (primarily because it doesn’t know what datatypes its dealing with). We augment this translation with a mapping from ranges to variable names and types, which in our experience can improve the percentage of correctly translatable formulas by about 5x. 4. We generate test cases for our translations as well, to make sure the Python process matches your Excel process. 5. We give you back a Jupyter notebook that contains the code we generated. If there are pieces of the Excel we can’t translate successfully (complex formulas, or pivot tables currently), then we leave them as a TODO in the code. This makes it easy for you to hop in and continue finishing the script. Who is this for: Developers who know Python, primarily! Pyoneer might be useful if: 1. You’ve got an Excel file you’re looking to move to Python (usually for speed, size, or maintenance reasons). 2. There’s enough logic contained in the notebook that it’s going to be a hassle for you to just rewrite it from scratch. 3. Or you don’t know the logic that is in the Excel workbook well since you didn’t write it in the first place :) Post translation, even if Pyoneer doesn't nail it perfectly or translate all the formulas, you'll be able to pop into the notebook and continue cleaning up the TODOs / finish writing the formulas. What the Alpha launch supports: Launched early! Currently we’re focused on supporting: 1. Any number of sheets, with any reference structure between them. 2. Cells that translate as variables directly. We’ll translate the formulas to Python code that has the same result, or else we’ll generate a TODO letting you know we failed translating this cell. 3. Tables that translate as Pandas dataframes. We support at most one table per sheet, at the tables must be contigious. If the formulas in a column are consistent, then we will try and translate this as a single pandas statement. We do not support: pivot tables or complex formulas. When we fail to translate these, we generate TODO statements. We also don’t support graphs or macros - and you won’t see these reflected in the output at all currently. Why we built this: We did YCS20 and built an open source tool called Mito( https://trymito.io ). It’s been a good journey since then - we’ve scaled revenue and to over 2k Github stars ( https://ift.tt/Qs6MqRl ). But fundamentally, Mito is a tool that’s useful for Excel users who wanted to start writing Python code more effectively. We wanted to take another stab at the Excel -> Python pain point that was more developer focused - that helped developers that have to translate Excel files into Python do this much more quickly. Hence, Pyoneer! I’ll be in the comments today if you’ve got feedback, criticism, questions, or comments. https://ift.tt/JAWgU04 May 23, 2024 at 11:10PM

Show HN: KraftCloud – The "Never Pay for Idle" Cloud Platform https://ift.tt/vVOSZzy

Show HN: KraftCloud – The "Never Pay for Idle" Cloud Platform Hi everyone, it’s Alex, Simon, Felipe and the team from Unikraft.io We have built kraft.cloud, a millisecond cloud platform, where apps and services cold start, scale to zero and autoscale in milliseconds, ensuring you never pay for idle, can efficiently cope with traffic peaks, and don’t have to deal with complex cold start issues. As of today we are now in open early access! The platform (and we) come from research in the area of lightweight virtualization — trying to ask the question of how efficient cloud platforms could (or should) be while still retaining strong, hardware-level isolation. KraftCloud is the result of this research followed by years of building the Unikraft open source project (www.unikraft.org). KraftCloud is based on unikernels, extremely specialized virtual machines, built on top of the Linux-API compatible Unikraft project. If you’ve heard of unikernels in the past, you’ve likely come across properties like millisecond cold start, small memory consumption, and small TCB, to name a few. You may have also heard of downsides like difficulty using them, debugging them, monitoring them or deploying them in the cloud — we’ve been hard at work tackling these issues. KraftCloud leverages Unikraft unikernels, but also comes with a custom-built controller that can be reactive in millisecond scales and can scale to thousands of instances on a single server. We also have integrations with Dockerfiles, Terraform and Kubernetes, and the ability to deploy within hyperscaler infra. The end result is a platform where - Cold starts take milliseconds (e.g., NGINX boots in 15ms) - Scale to Zero (and scale back up) also takes milliseconds - Autoscale takes milliseconds so you can transparently cope with fast peaks - We can put 1000s of instances on a single server, reducing cost and carbon footprint We’re in open early access and are actively handing (free) access tokens via the sign up form here: https://ift.tt/OB1mLTC We would really appreciate as much feedback as humanly possible: what you like, what you don’t like, what isn’t clear, what we’re missing, what’s broken, etc (you can find more information in our FAQs: https://unikraft.io/faq , or this blog post: https://ift.tt/zfNHJiG Thanks so much for reading all the way to the end and looking forward to your comments! https://kraft.cloud/ May 22, 2024 at 08:14PM

Show HN: B-field, a novel probabilistic key-value data structure (`rust-bfield`) `rust-bfield` is a Rust implementation of our novel "B-field" data structure, which functions like a Bloom filter for key-value lookups instead of set membership queries. The B-field allows you to compactly store data using only a few bytes per key-value pair. We've successfully utilized it in genomics to associate billions of "k-mers" with taxonomic identifiers while maintaining an efficient memory footprint. But the data structure is also useful beyond computational biology, particularly where you have large unique key domains and constrained value ranges. Available under an Apache 2 license. We hope it proves useful, and we're happy to answer any questions! https://ift.tt/wofngAm May 22, 2024 at 11:23PM

Show HN: SQLFrame – I ran PySpark without Spark on a SQL database https://ift.tt/VctreJE

Show HN: SQLFrame – I ran PySpark without Spark on a SQL database Recently I open-sourced SQLFrame, a DataFrame library that implements the PySpark DataFrame API but removes Spark as a dependency. It does this by generating the corresponding SQL for the DataFrame operations using SQLGlot. Since the output is SQL this also means that the PySpark DataFrame API can now be used directly against other databases without the Spark middleman. I built this because of two common problems I have faced in my career: 1. I prefer to write complex pipelines in PySpark but they can be hard to read for SQL-proficient co-workers. Therefore I find myself in a tradeoff between maintainability and accessibility. 2. I really enjoy using the PySpark DataFrame API but not every project requires Spark and therefore I'm not able to use the DataFrame library I am most proficient in. The library currently focuses on transformation pipelines (reading from and writing to tables) and data analysis as key use cases. It does offer some ability to read from files directly but they must be small although this can be improved over time if there is demand for it. SQLFrame currently supports BigQuery, DuckDB, and Postgres with Clickhouse, Redshift, Snowflake, Spark, and Trino in development or planned. You can use the "Standalone" session to test running against any engine supported by SQLGlot but there could be issues with more advanced functions that will be resolved once officially supported by SQLFrame.

Show HN: Drivr – VR with real vehicles [video] https://ift.tt/iOvfqlt

Show HN: Drivr – VR with real vehicles [video] This project combines VR with a real vehicle that you are controlling (or is controlling itself, in some scenarios). One advantage this has over traditional VR motion experiences is that your senses all agree with each other, thus greatly reducing the likelihood of motion sickness. The go-kart seen in this video is drive-by-wire and steer-by-wire, so the system will not let the player exit the defined safe area. If a player goes off course, the vehicle will take control, and return them to the start. The autonomous capabilities also allow for games where the player can focus on other objectives other than driving, such as target shooting. No infrastructure is required other than the vehicle and an open place to drive (which honestly has been the most challenging part lately). If you're interested in this project, I'd love to connect! https://www.youtube.com/watch?v=Q76X0cnSGHk May 17, 2024 at 12:49AM

Show HN: A job board that helps you find impactful roles https://ift.tt/TqWma4n

Show HN: A job board that helps you find impactful roles Hi everyone! We wanted to make it easier for people to find high-impact roles across various fields, so we built a job board that highlights relevant opportunities. We’re a nonprofit, so this is completely free. When we say “high-impact”, we mean that we think these roles are relatively likely to lead to substantial positive change in the world. We recognize that there’s a lot of uncertainty regarding this, since although we look into the jobs that we list, there’s no way to be sure which ones will end up being impactful (not to mention that people have different definitions of “high” and “positive” impact). We also know that not everyone prioritizes this kind of impact, especially given how hard the job-search process can be. But, we still think there’s value in trying to aggregate these kinds of jobs, in order to help interested people find them. https://ift.tt/r5BU8ej May 16, 2024 at 07:48PM

Show HN: PuppySignal, an open-source QR Tag for your pets A few years ago, I started working on a side-project just for my own use: a QR Tag for my pets. I decided to open-source it for anyone who might find it useful. The functionality is pretty simple: when you log in, you create a profile for your pet, and a QR code will be generated and linked to its profile. When someone scans this code and decides to share your pet's location, you will receive a notification on your phone with your pet's location, and the person who scanned it will see your contact information. https://ift.tt/lPhWxVg May 13, 2024 at 10:50PM

The rationale behind it is while wireguard is a fantastic protocol cryptographically it leaves a lot to be desired when it comes to enrollment and end user device security. Obviously instead of using an off the shelf solution like tailscale, I decided to reinvent the wheel which has honestly been quite fun with learning about eBPF, and recently clustering and HA with etcd! The most recent version (in the docker container) contains about 6 months of very new work bringing it all from sqlite3 to etcd. So please be forgiving if it does some weird things! Hope you all enjoy! P.s Im not a web developer and any tips on that front to make it less teeth pullingly awful are welcome! https://ift.tt/JlobAiD May 11, 2024 at 01:01PM

Show HN: MinimalChat – A Simple and Customizable LLM Chat Application Hello everyone! I have a hobby project that has become fairly full featured that I figured I would share. The idea of MinimalChat has been to create a project that is a lightweight and dead simple application that can be deployed locally in a few seconds (with docker). While of course also having most of the nice to have features and looking pretty nice. A nice bonus is it a Progressive Web Application so it can be installed like a normal application to your mobile device. It has a full mobile UI. For those using Chrome and Edge you can also locally download, load and host entirely via your browser models like LLama-3-8b with hardware acceleration via WebGPU. It's pretty experimental but it does work! I won't bloat this post reiterating it's features, the GitHub Readme gives a good idea of the application abilities. I know chat applications are a dime a dozen but...here's another one hah! https://ift.tt/xzNyKHR May 11, 2024 at 09:19AM

Show HN: AI Runner – my personal opensource, local, multi-modal, AI assistant https://ift.tt/svrM4ak

Show HN: AI Runner – my personal opensource, local, multi-modal, AI assistant AI Runner is an application I have been working on for well over a year. I am the only developer on the project. I currently do not have a job so I have treated this as my full-time job. 3.0 is not yet ready for release, but I wanted to show you some of the cool things I've done with it (see video in link or check out my youtube page for past progress updates https://www.youtube.com/@capsizegames4331 ). AI Runner is a privacy-forward, multi-modal offline AI application built with Pyside6, huggingface libraries, llamaindex and open source models. It allows for real-time text to speech conversations with chatbot agents that you can fully customize. The bots have personalities and "moods". The moods shift with the conversation. I am using custom agents and my own system for selecting actions which is very fast. The application also allows you to generate images using Stable Diffusion and controlnet (previous versions allowed Kandinsky), LLM for chatbots and RAG retrieval using Mistral 7b and T5, multi-lingual text-to-speech using speech-t5, bark and espeak. The whole thing can run on a single 2080s video card, or you can split it between multiple GPUs by assigning models to available cards. For example, I have a 2080s which I use for Stable Diffusion, and a 3060 that I use for the other models. I've built in lots of features such as drawing tools, RAG for documents and websites, image generation with the LLM or custom prompts and more. I post about it often on my Twitter acount ( https://twitter.com/xw4ffl35x ). In addition to being a stand-alone application, the goal is to make it usable as an engine to power other applications. For example I plan to use it to power an RPG I am developing in Pygame. The application is pure python and can be compiled with pyinstaller using the installation scripts included in the main repo ( https://ift.tt/5gwj0lh ). I am currently working on v3.0.0 which is under heavy development and is not stable. The last stable version came out over 8 months ago and was version 2.2 (you can find it tagged on github). This new version is a complete refactor and uses proper threading, has enhanced privacy and security features (the app is not able to access the internet and complete works around any security holes in the huggingface libraries by preventing them from accessing the internet or creating a .cache folder - there's more information about this in the README). --- I believe it is crucially important to have open source options when it comes to AI. I do not want to live in a world that is dominated by OpenAI. I want free, open source models and the ability to run them locally, offline for free. If you would like to support my efforts, please consider donating via patreon https://ift.tt/Lw7cIEh https://twitter.com/xw4ffl35x/status/1778094355812700635 May 11, 2024 at 02:12AM

Show HN: A web debugger an ex-Cloudflare team has been working on for 4 years https://ift.tt/RGBvXEM

Show HN: A web debugger an ex-Cloudflare team has been working on for 4 years Hey HN, I wanted to show you a product a small team and I have been working on for 4 years. https://jam.dev It’s called Jam and it prevents product managers (like I used to be) from being able to create vague and un-reproducible bug tickets (like I used to create). It’s actually really hard as a non-engineer to file useful bug tickets for engineers. Like, sometimes I thought I included a screenshot, but the important information the engineer needed was what was actually right outside the boundary of the screenshot I took. Or I'd write that something "didn't work" but the engineer wasn't sure if I meant that it returned an error or if it was unresponsive. So the engineer would be frustrated, I would be frustrated, and fixing stuff would slow to a halt while we went back and forth to clarify how to repro the issue over async Jira comments. It’s actually pretty crazy that while so much has changed in how we develop software (heck, we have types in javascript now*), the way we capture and report bugs is just as manual and lossy as it was in the 1990’s. We can run assembly in the browser but there’s still no tooling to help a non-engineer show a bug to an engineer productively. So that’s what Jam is. Dev tools + video in a link. It’s like a shareable HAR file synced to a video recording of the session. And besides video, you can use it to share an instant replay of a bug that just happened — basically a 30 second playback of the DOM as a video. We’ve spent a lot of time adding in a ton of niceties, like Jam writes automatic repro steps for you, and Jam’s dev tools use the same keyboard shortcuts you’re used to in Chrome dev tools, and our team’s personal favorite: Jam parses GraphQL responses and pulls out mutation names and errors (which is important because GraphQL uses one endpoint for all requests and always returns a 200, meaning you usually have to sift through every GraphQL request when debugging to find the one you’re looking for) We’re now 2 years in to the product being live and people have used Jam to fix more than 2 million bugs - which makes me so happy - but there’s still a ton to do. I wanted to open up for discussion here and get your feedback and opinions how can we make it even more valuable for you debugging? The worst part of the engineering job is debugging and not even being able to repro the issue, it’s not even really engineering, it’s just a communication gap, one that we should be able to solve with tools. So yeah excited to get your feedback and hear your thoughts how we can make debugging just a little less frustrating. (Jam is free to use forever — there is a paid tier for features real companies would need, but we’re keeping a large free plan forever. We learned to build products at Cloudflare and free tier is in our ethos, both my co-founder and I and about half the team is ex-Cloudflare) and what we loved there is how much great feedback we’d get because the product was mostly free to use. We definitely want to keep that going at Jam.) By the way, we’re hiring engineers and if this is a problem that excites you, we’d love to chat: jam.dev/careers May 10, 2024 at 06:38PM

Show HN: Loglayer: A fluid logging interface for JavaScript loggers https://ift.tt/Sn2vwRt

Show HN: Loglayer: A fluid logging interface for JavaScript loggers This has been in use on our production systems for around two years now at Switchboard ( https://switchboard.app ). The problem we had was that we were using two different logging libs for our frontend and backend at the time, and the API for the logging libs were not compatible with each other. Loglayer was designed to wrap around popular JS logging libraries where you can swap out any underlying library without re-writing your log entries to adapt to the new library. One common example is using plain "console" as a starting integration, but later swapping to a logging library like Winston once you've nailed down which JS logging lib fits your use-case. It also provides a fluid API that standardizes how one should feed errors and set context and metadata. This means regardless of the underlying logging library used, developers use the same API to write logs throughout. log .withMetadata({ some: 'data'}) .withError(new Error('test')) .info('my message') With this new 4.x release, I added a plugin system allowing you to manipulate data before it is shipped to the underlying JS logger). https://ift.tt/wMv5tNS May 10, 2024 at 12:15AM

Show HN: I made a calculator builder to increase engagement and conversions Hi HN, I am a solopreneur in the evenings and a software engineer during the day. In the past, I have created lots of calculators for my web projects and freelancing friends. These were pretty basic, but users always welcomed them. I also used currently available builders, but the problem was that they were either slow, broke on mobile devices, had nonsense page view limits, or were expensive. Some even ticked all those boxes. So I have decided to create my own, with a simple interface, and called it Creative Widgets (if it ever takes off, I plan to add more exciting stuff like charts, etc, hence why generic “Widgets”). At this point, I am after feedback. I found myself running in a circle, building features because I think they're great to have, but I would much rather have features that are wanted by users. So, if your project/web benefits from the custom calculator, you can check it out. Thanks everyone. Eugen https://ift.tt/iEWPSAT May 8, 2024 at 02:24AM

Show HN: An AI model that busts AI faces https://ift.tt/BbRLw6v

Show HN: An AI model that busts AI faces Hey HN, I'm an AI enthusiast and I am launching apps that use ML to solve problems that we all have. I realized that there are a lot of deepfake faces on youtube and social media, so I thought it would be useful (and fun!) to have a tool that can bust those AI faces. So I built DeeFace for 2 reasons: 1. Check if the face you're looking at is real or not 2. For fun! It's something that I from half a year ago would look at and aspire to build someday. I think it's soemthing anyone who's just starting out with ML would appreciate. I hope this tool is fun for you to use as it was for me to build. Would love to hear your feedback on this.

Show HN: I built a website to share files and messages without any server https://ift.tt/ymF230I

Show HN: I built a website to share files and messages without any server NeighborHoodShare: It is a p2p files and messages sharing platform without involvement of any server. It has end-to-end encryption, ensuring your messages and files remain confidential. These are some features: - Share photos, documents, videos, and more with ease, no matter the size. - Connect instantly with anyone for speedy and reliable file transfers, bypassing the need for centralized servers. - Get started in minutes with our intuitive interface designed for seamless communication. No registration. - Easily connect with others using QR codes, simplifying the sharing process further. The inspiration behind NeighborHoodShare stemmed from a common dilemma: the reluctance to share personal contact details like phone numbers or email addresses when sharing photos or messages with strangers. With NeighborHoodShare, you can share content securely without compromising your privacy. I would be happy to hear your feedback and suggestions for improving NeighborHoodShare. I had written a blog on how p2p networking in browsers work: https://ift.tt/KLGOVTU... https://ift.tt/HpEA7Oc May 5, 2024 at 01:12PM

Show HN: gpudeploy.com – "Airbnb" for GPUs https://ift.tt/PZUshLB

Show HN: gpudeploy.com – "Airbnb" for GPUs Hi HN, YC w24 company here. We just pivoted from drone delivery to build gpudeploy.com, a website that routes on-demand traffic for GPU instances to idle compute resources. The experience is similar to lambda labs, which we’ve really enjoyed for training our robotics models, but their GPUs are never available for on-demand. We are also trying to make it more no-nonsense (no hidden fees, no H100 behind “contact sales”, etc.). The tech to make this work is actually kind of nifty, we may do an in-depth HN post on that soon. Right now, we have a H100s, a few RTX 4090s and a GTX 1080 Ti online. Feel free to try it out! Also, if you’ve got compute sitting around (a GPU cluster, a crypto mining operation or just a GPU) or if you’re an AI company with idle compute (hopefully not in a Stability AI way) and want to see some ROI, it’s very simple and flexible to hook it up to our site and you’ll maybe get a few researchers using your compute. Nice rest of the week! https://ift.tt/Zn4Uji8 May 5, 2024 at 02:33AM

Show HN: Dillo 3.1.0 released after 9 years As commented before[1], I've been working on the past months to get the Dillo back to life and today I'm happy to release the 3.1.0 version, after almost 9 years since the last one. [1]: https://ift.tt/nxy5rVA During this time: - A new mailing list was created[2] which is beginning to get some messages and patches. It is available in gmane via NNTP at gmane.comp.web.dillo.devel. [2]: https://ift.tt/iO29WUN... - A LiberaPay page[3] which received the first donations (thanks!). [3]: https://ift.tt/kw1y0FP - Some more bugs where fixed and new features where added (details in the release page and/or changelog). Thanks to all the people that contributed with patches and tests. Now let's see if we can make it land in some distros! https://ift.tt/F3HG9RC May 5, 2024 at 01:52AM

Show HN: I built a free in-browser Llama 3 chatbot powered by WebGPU https://ift.tt/GofFDlR

Show HN: I built a free in-browser Llama 3 chatbot powered by WebGPU I spent the last few days building out a nicer ChatGPT-like interface to use Mistral 7B and Llama 3 fully within a browser (no deps and installs). I’ve used the WebLLM project by MLC AI for a while to interact with LLMs in the browser when handling sensitive data but I found their UI quite lacking for serious use so I built a much better interface around WebLLM. I’ve been using it as a therapist and coach. And it’s wonderful knowing that my personal information never leaves my local computer. Should work on Desktop with Chrome or Edge. Other browsers are adding WebGPU support as well - see the Github for details on how you can get it to work on other browsers. Note: after you send the first message, the model will be downloaded to your browser cache. That can take a while depending on the model and your internet connection. But on subsequent page loads, the model should be loaded from the IndexedDB cache so it should be much faster. The project is open source (Apache 2.0) on Github. If you like it, I’d love contributions, particularly around making the first load faster. Github: https://ift.tt/fz3QVqD Demo: https://secretllama.com https://ift.tt/fz3QVqD May 4, 2024 at 02:56AM

Show HN: Prompt Tower – Simplify writing prompts with multiple code blocks https://ift.tt/QViloyK

Show HN: Prompt Tower – Simplify writing prompts with multiple code blocks Prompt-tower simplifies and speeds-up how prompts with multiple code blocks are written. It's often a pain jumping between files, classes, functions, etc and copying/pasting everything, wrapping and annotating the blocks, and finally sending the prompt off for generation. After seeing filekitty [1], I felt inspired to build a version of the idea I’ve had for awhile now... which is a vscode extension that fits better in a developer's context. check it out: https://ift.tt/No80cte... demo gif: https://ift.tt/Qf3Ahlp repo: https://ift.tt/GkTpw4c [1] https://ift.tt/LHKjDyu May 3, 2024 at 11:40PM

Show HN: Bathroom App – Find bathrooms near you https://ift.tt/2sfKi0U

Show HN: Bathroom App – Find bathrooms near you Hey HN! We created Bathroom App - a free webapp to find bathrooms. Currently live in San Francisco. I've lived in SF, NYC and Vancouver and while all of these cities are very different, one thing that's shared is that it's a struggle to find bathrooms. I've had close calls where I've ran to 2-3 different places asking to use their bathroom before finally finding one. It's stressful and COVID has made it even harder. A "toilet finder" is not a new idea but the existing apps are disappointing. I've tried them all and they're either littered with bad data or don't have important information like access details (e.g. codes), cleanliness ratings, amenities(tampons, baby changing table etc.) and bathroom type (gender neutral, private or shared etc.). The challenge is for this to be helpful, the data needs to be there and it needs to be reliable. Our playbook is to launch in a major city > collect seed data ourselves > allow user input > manually verify new bathroom submissions or edits. For example, in San Francisco, we added publicly available data. Then, we added chains that have free bathrooms like Target, Safeway etc. And finally, we identified bathroom deserts, walked around those areas and mapped free bathrooms (we did that for 100+ bathrooms...it took a while). The result is a map that's valuable to people on day 1 - and we've already had locals contributing to it since we've launched. I've found that people who are particular about cleanliness, travel a ton or have IBS appreciate this product the most. But for most people, it's the kind of product you may not need daily, but when you DO need it, you'll be thankful for its existence :) https://ift.tt/BKlR4ch May 2, 2024 at 01:19AM
